Bosch EXPERT HEX-9 HardCeramic Drill Bit Set, Hex Shank, 3 pieces, 5–8 mm

The Bosch EXPERT HEX-9 HardCeramic Drill Bit Set is a 3-piece carbide tile drill bit set designed for hard, brittle surfaces. The bits use a durable construction to keep a sharp cutting edge when drilling into dense materials. A centering tip gives immediate control at the start of the hole and prevents the bit from wandering on smooth finishes. The bits can be used on glass, hard ceramic, soft tile, roofing tile, and stone, producing clean, accurate holes without cracking or splintering the surface.

The standard hex shank fits rotary drills and impact drivers, holding firmly in the chuck to reduce slippage under load. The set covers common installation needs with diameters of 5, 6, and 8 mm. Each bit is 90 mm long, enough to pass through standard tile thicknesses and into the wall behind. A stainless steel body supports the carbide cutting edges and keeps the bit stable during continuous use.

• 5, 6, and 8 mm working diameters cover the most common wall plug sizes for standard fixtures.
• Carbide cutting edges resist dulling on abrasive roofing tiles and hard stone.
• Centering tip allows accurate starting on smooth glass and ceramic without pre-taping.
• Hex shank gives a secure, slip-free hold in compatible rotary drill and impact driver chucks.
• 90 mm overall length lets the bit pass through thick exterior tiles and into the substrate behind.
